With the advent of OFDM for WLANcommunications, as exemplified by IEEE 802.11a, it has becomeimperative to have efficient and reliable synchronizationalgorithms for OFDM WLAN receivers. The main challengeswith synchronization deal with the frequency offset and delayspread introduced by the wireless channel. In this paper,research is done into OFDM timing synchronization andfrequency synchronization techniques.one symbol...

[unknown]Lectures on Image Processing - Alan Peters
Updated 11 March 2013 There was an error in the Fourier Transform lecture (No. 6). The calculation of the wavelength of a Fourier component from its position on the Fourier plane was incorrect. That has been corrected. Please download the latest version. ----- This is a 20-lecture series on Image Processing that I have created over the past 14 years (1999-2013) for my course, EECE/CS 253, at the Vanderbilt University School of Engineering...

 Interharmonics are the non-integral multiples of the system’s fundamental frequency. The interharmonic   components can be apprehended as the intermodulation of   the fundamental and harmonic components of the system with   any other frequency components introduced by the load. These   loads include static frequency converters, cyclo-converters,   induction motors, arc furnaces and all the loads not pulsating   synchronously with the fundamental frequency of the system...

R&D Report 1995-03 : Controlled Image Design: The measurement of Time-Frequency responses. R. Walker This Report describes the measurement of acoustic events in a 3-dimensional measurement domain. An outline of the general theoretical background is followed by a description of the special requirements for the measurement of short-term acoustic responses in rooms. The results of measurements on an experimental synthesis of a single room reflection are also presented...
